The levels of neurocyte damage markers, apoptosis markers and stress markers in serum as well as the expression of Wnt pathway molecules in peripheral blood were determined before treatment and 24 h after treatment.Results: Compared with those of same group before treatment, serum NSE, S100B, VILIP1, sFas, sFasL, ET-1 and MDA levels as well as peripheral blood GSK3β, LC3-II and Beclin1 expression intensity of both groups were decreasing whereas serum BDNF, NTF, sLivin and SOD levels as well as peripheral bloodβ-catenin and mTOR expression intensity were increasing, and serum NSE, S100B, VILIP1, sFas, sFasL, ET-1 and MDA levels as well as peripheral blood GSK3β, LC3-II and Beclin1 expression intensity of study group A after treatment were lower than those of study group B whereas serum BDNF, NTF, sLivin and SOD levels as well as peripheral bloodβ-catenin and mTOR expression intensity were higher than those of study group B.Conclusion: Mechanical embolus removal for acute middle cerebral artery occlusion can be more effective than intra-arterial thrombolysis to reduce the nerve function damage as well as the corresponding oxidative stress and apoptosis.展开更多

The mucosal lesions had been initially diagnosed as oral lichen planus and resistant to various treatments with prednisolone, etretinate and mizoribine and so on. One year ago, rapidly growing verrucous lesion occurred on her upper lip. Although we administered intralesional radiation therapy, the tumor recurred and new whitish lesions on the buccal mucosa and hard palate occurred 9 months after treatment. We confirmed an anatomical blood supply to the tumors by a fluorescent real-time imaging system and subsequently administered the intra-arterial infusion of peplomycin through retrograde catheters from bilateral superficial temporal arteries under the final diagnosis as oral florid papillomatosis (OFP). The tumors were dramatically shrunk and did not recur 16 months after treatment. OFP is known as clinically multiple whitish and verrucous lesions over the oral cavity and lip and a subtype of SCC with high differentiation. We suppose that an intra-arterial infusion therapy of peplomycin should be considered as the curative treatment for OFP.展开更多

However, effective treatments for patients with acute ischemic stroke are limited. Intravenous recombinant tissue plasminogen activator(iv rtPA) within 4.5 h after onset has been approved as a standard treatment for patients with acute ischemic stroke. However, due to time constraints, less than one percent of acute ischemic stroke patients in Thailand are able to obtain iv rtPA. Although endovascular interventional therapy has not yet been approved as standard treatment in acute ischemic stroke, it is the one of the potentially effective treatment options. There are several reliable methods of endovascular therapy for acute ischemic stroke patients. Endovascular interventional therapy has rarely been done in Thailand. We report seven patients with successful recanalization after endovascular treatment in acute large vessel stroke from a single stroke center in Thailand. Patient screening and selection with multimodal imaging protocol and multimodality methods of endovascular interventional therapy are described.展开更多
